Leners Patent No. 91,622, dated Jua@ 22, 1869.

IMPRQVEMENT IN CURB-AG-ITATORS.

Wr-w* 'The Schedule referred to in these Lettera Patent making part ofthe same.

0To all whom it may concern.-

Beit known that I, DE WITT C. HALL, 'of Barnes Corners, in thevcounty ofLewis, and State of New York, have invented a new and improvedCurti-Agitator; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make'and use the same, reference being had to theaccompanying drawings, forming part of this specication.

This invention relates to improvements in apparatus for stirring curd,`and separating the whey therefrom, preparatory to making cheese.

It' consists of the arrangement in a vat, having a -metallic or otherscreen near the bottom, of a sliding and rotating stirring-"apparatus,whereby the curd is agitated, and the whey ca used to pass oi' throughthe screen,as will be hereinafter specified. Y

Figure l represents a longitudinal sectional elevation of my improvedapparatus; andl 1 Figure 2represents aplan View, showingthe screenpartly broken away.

Similar letters of reference indicate corresponding parts.

Avrepresents a yat, preferably made of wood, of rectangular forni,having a screen, B, arranged a shortedistance above the bottom,preferably made of zinc, gal-V vanizediron, or metalwhich will notcorrode readily.

C -represents a-shaft, arranged transversely upon the vat, in bearin gs,D,`capableof sliding to and fro thereon. E represents toothed racks,upon the top ofthe sides of the vat, and

F represents the racks.

The shaft Gis provided with beaters, G, arranged spirally around it, andreaching nearlyto the screen. The said beaters are considerablyflattened at the ends,

pinions on the shaft C, gearing into and the ends 'arrangedangularly totheir planes of rotation.

Hrepresents Scrapers, suspended on each side of fthe beater-reel,transverselyot' the vat, from supports rotary vmotion of the shaftcausing it to slide also, by

means of the pinions.A 'The motion of the hand-crank is reversed whenthe apparatus arrives at either end.

When the beater-cylinder is moving along the vat, the tbllowing-scraperH will be drawn under the curd along the screen, and the curd will bethereby raised, to allow the whey tostrain through the screen.

The supports of the Scrapers may be turned in either direction by. hand,att-he end of the movement of the beater-cylinder, to cause the saidScrapers to assume thejrproper position at starting into the oppositemovement'. Y

kBy this arrangement, the work of stirring, cooling, salting, andstraining the -curd may be rapidly and economically accomplished.'

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent-'- 1. Thecombination of thevat A,'screen B, and'rol tary and sliding beating-armsG, substantially as specified.

2.' The combination of the sliding and rotating beat# ing-arms G andScrapers H, substantially-as specified.
